Split build & deploy scripts (#1239)

## Description:

Split deploy.sh into build.sh & deploy.sh (deploy only)

build.sh builds & pushes the docker image
deploy.sh copies the update.sh into machine, pulls the image, and runs
it.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

## Please put your Discord username so you can be contacted if a bug or
regression is found:
